Permo® therm

The new complete rafter insulation, Permo® therm is characterised by high performance insulation with vapour permeable SK2 membrane laminated onto the outer surface. This combination helps drying of the roof due to its ability to dispel water vapour. Permo® therm with Thermo-Line sealing products, allows the whole roof area to be air-tight, windproof and free of thermal bridges.
